UMBRELLA-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,493, dated Marchl0, 1885.

Application filed January 9, 1884. (No model.)

To all whom t may concern.-

Beit known that I, E. HARRIsoN GRIFFIN, a citizen of the United States,residing in the city of New York, in the county and State of New York,have invented certain new and useful Improvements in Locking Devices forUmbrellas, of which the following is a specification.

My invention relates to a lock to be applied to an umbrella, so thatwhen not in use it may be locked or fastened so as not to be opened byone unfamiliar lwith the mode of operation; and it consists of thedevices shown in the drawings and hereinafter described.

In the drawings, Figures l and 2 show different methods of applying mydevice so as to fasten an umbrella, the lock being in position to holdthe umbrella closed. Fig. 3 is a sectional view of one of the movabledouble rings B. Fig. 4 is a cross-sectional view of the same. Fig. 5 isan exterior side view of one of the movable rings shown in section inFigs. 3 and 4, with combination-letters thereon. Fig. 6 is a plan viewof the sliding tube with the fixed rings and one ofthe movable doublerings thereon. Fig. 7 is the same in section with the movable doublering omitted, and Fig. 8

a section of the sliding tube and fixed ring.

The same letters of reference refer to similar parts in all thedrawings.

A is the stick of the umbrella, and C a tube sliding freely thereon. Thetube C may be either the runner to which the rib-braces c c arefastened, or it may be a tube working separately and placed on the.'stick A below the rib-cap H, as shown in Fig. 2.

On each end of the tube C are placed the fixed rings C U', which may loeformed by turning back the ends of the tube C, or by soldering to thetube C a ring having one edge turned down in a ange.

On the outside of the tube C, and between the xed rings C C, are placedthe double movable rings B B, of which I use, preferably, two, thoughthere may be three or more, and of such width as to completely fill thespace between the fixed rings C C'. The double rings B B consist of anouter ring, D, and an inner ring, E, soldered to the outer ring, as ath, and having a slot, F, as shown in Fig. 4. The tube C has cut in itthe slot G, extending lengthwise, and so placed and of such length thatthe spring S shall set up through the slot G and hold the tube C inposition when the slot is moved overthe spring, and the slotsF in theinner ring, E, are coincident with the slot G.

On the movable rings B B and the fixed rings G are marked letters orfigures, as shown in Fig. 6, of which there may be any number, and soplaced that when certain letters on the movable rings are in line withthe proper ones on the fixed rings the slots in the inner rings, E, willbe directly over the slot G.

The mode of operation is as follows: When the umbrella is closed, theslot F being over the slot G, the spring S stands up in the slot G andthe tube C is held in place. The double rings B B are then moved so thatthe inner ring, E, passes under the spring S, thus holding it betweenthe inner and outer rings and preventing it from being pressed down intothe recess provided for it, thus making the moving of the tube C alongthe staff, and consequently the opening of the umbrella, impossibleuntil by turning the rings so as to form the proper combination of theletters thereon the slots F are again brought over the slot G. Thespring S will then give way into the recess in the staff, when the `tubeC is pushed against it and permit the opening of the umbrella.

Vith such a device the locking mechanism is entirely concealed fromview, and it is impossible to open the umbrella until all the slots Fare brought over the slot G.

Any desired. degree of intricacy in the combination may be obtained byincreasing the number of the movable rings B B.

Instead of applying the locking device to the tube to which therib-braces are attached, it may be employed as shown in Fig. 2. Here aseparate tube C is placed on the umbrellastaff below the sliding cup H,which fits over the ends of the ribs. When the umbrella is closed, thecup H is slipped up so as to confine the ends of the ribs, and the tubeC is then pushed against'it, and then locked by means of the spring Sand movable rings B B, as before. TWhen I apply the device in this way,I bend the rib-tips a: .fr at right angles, or

ymake them somewhat larger than usual, so

that they may be firmly held within the lip or fiange ofthe cup H.

I am aware that combination-locks having Ioov letters and figuresthereon have been heretofore applied to umbrellas, and I do not broadlyclaim such device as a part of my invention.

What I do olaim as new, and desire to secure by Letters Patent, is-

1. The eombination,with the staff' of an um- 2. The combination, withthe retainingspring of au umbrella or parasol and the runner-tubethereof, of one or more double rings, B, formed of a complete outerringr and aslotted inner ring, the inner ring being adapted to engageunder the spring and prevent its brella, of a movable tube, O, providedwith l being pressed down, substantially asset forth. fixed rings C andmovable double rings B, each formed of a complete outer ring and aslotted inner ring firmly fastened thereto having letters or gures ontheir outer surface, substantially as and for the purposes set forth.
